Demonstration of a sparse sensor placement technique to the limited diagnostic set in a fusion power plant [PDF]

DEMO will have a limited diagnostic set for optimization of reactor performance, and limited diagnostic coverage due to challenging reactor conditions. This poses challenges for control, especially for detachment control which is planned to be performed ...

Towards self-consistent integrated modeling of the tokamak pedestal, scrape-off layer, and divertor using SOLPS-ITER and EPED

Nuclear Fusion
A predictive, self-consistent integrated model of the tokamak edge plasma and neutral system has been developed and validated against experimental data from DIII-D, spanning from the divertor target and scrape-off layer to the top of the pedestal.

Experiment-modeling studies comparing energy dissipation in the DIII-D SAS and SAS-VW divertors

Nuclear Materials and Energy
Recent DIII-D experiments on Small Angle Slot (SAS) divertors have confirmed that a combination of divertor closure and target shaping can enhance cooling across the divertor target and increase energy dissipation, but with significant dependence on BT ...

Investigating the influence of divertor baffles on nitrogen-seeded detachment in TCV with SOLPS-ITER simulations and TCV experiments

Nuclear Fusion
Plasma edge simulations with the SOLPS-ITER code are performed to study the influence of divertor baffles on nitrogen-seeded detachment in Tokamak à Configuration Variable (TCV) single-null, L-mode discharges. Scans of nitrogen seeding rate are conducted

Comparison of divertor seed impurity gases retention efficiency by SOLPS-ITER modeling

Nuclear Fusion
Abstract In the paper a SOLPS-ITER modeling of H-Mode scenarios with different seed impurity gases (N, Ne, Ar, Kr) is performed for ASDEX Upgrade geometry. These gases are compared from the point of view of their radiation efficiency and compression in the divertor, which is generally understood as the ratio of the divertor to upstream ...

Novel inferences of ionisation & recombination for particle/power balance during detached discharges using deuterium Balmer line spectroscopy

, 2019
The physics of divertor detachment is determined by divertor power, particle and momentum balance. This work provides a novel analysis technique of the Balmer line series to obtain a full particle/power balance measurement of the divertor.

Application of an automated grid deformation tool for divertor shape optimization in SOLPS‐ITER

Contributions to Plasma Physics
AbstractAn optimized divertor design is crucial to maximize the lifetime of plasma‐facing components and reduce costs of future fusion power plants. Numerical shape optimization could be a powerful tool to obtain improved designs in an automated way.

Non-monotonic energy flux density profiles at the ITER divertor entrance

Nuclear Fusion
SOLPS-ITER simulations of the ITER baseline ( Q  = 10) plasma boundary, with tungsten (W) targets and drift terms activated, exhibit a radially localised peak in the energy flux density entering the outer divertor, despite constant anomalous transport ...
